PHYSICAClass 12 Physics simulations · Dual Nature of Radiation and Matter
Matter-wave wavelength
Accelerate an electron through a potential difference and calculate its wavelength.
What to notice
Increasing kinetic energy shortens the de Broglie wavelength.
Key relation
λ = h/√(2meV)
Try this
Quadruple the accelerating voltage.
What you can change
- Accelerating voltage: 10 to 1000 V
